If autoconf > 2.69 ; simply download, make, make install -/usr/local/bin/autoconf <- first in your path Because of different install location, check the Makefile path, might need to adjust the path as 'sed' below

http://espressif.com/en/products/esp8266/
: Espressif is the manufacturer of the ESP8266. Their site is pretty
much a bunch of marketing hoo-hah and you'll have to "contact" them for
more information. Not too useful.

https://nurdspace.nl/ESP8266
: This is the homepage for a lot of ESP8266 information.

https://www.zybuluo.com/kfihihc/note/31135:
This is the earliest design example I have found. It uses the ESP8266
WiFi module to grab a static page from the internet.

http://rayshobby.net/?p=9734
: This is another early, complete design example. (This site seems to
be up and down, so keep checking if you can't get to it.)

http://hackaday.io/project/3072/instructions
: This is another complete example that uses the ESP8266 to provide the
internet link for a simple web browser hosted on an Arduino.

http://www.esp8266.com/
: This is a community forum centered around the ESP8266.Everythingis
here, but probably best to read this stuff after going through a
complete design example.

This
is a list of all the Github repositories I could find with ESP8266 code.

https://github.com/esp8266
: Repo for the ESP8266 community forum.

https://github.com/bafeigum/ESP8266-Library
: Looks like an Arduino continuously polls the ESP8266 and prints a
list of any Wifi access points it finds. I didn't think too much of
this app at first until I looked at some of the others.

https://github.com/imjosh/espBasicExample
: This might be an actual, working example of using the ESP8266 with an
Arduino. Worth a look.

https://github.com/scottjgibson/esp8266
: I'm not really sure what this is, but there's a lot of it.

https://github.com/534659123/OCROBOT-WIFI-ESP8266-arduino-library
: This seems to be some test code for another type of ESP8266 board
with a 6-pin connector. I'll pass.

https://github.com/aabella/ESP8266-Arduino-library
: Looks like a project stub. Not complete.

https://github.com/giannoug/ESP8266
: Another "work-in-progress" project (by the author's own admission).
Not complete.

Here's
a list of all the ESP8266 tutorials I've made using the information
provided from the above sources. Hopefully I've accurately distilled
their knowledge into a concentrated elixir that will answer your
questions on certain, specific topics:
